JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 741,021, dated October A 13, 1903.

Application filed January 2, 1903. Serial No. 137,466. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES ERIOKSON, a citizen of the United States, residing at St.

Louis, in the State of Missouri, have invented crease the durability, to lessen the friction on.

that class of bearings, and to make it possible to run cars thus equipped at a higher even rate of speed than is usually attained with a poorer construction and a combination of metals not evenly distributed on its wearingsurface. I attain these objects by themechanism illustrated in the accompanying drawings, in Which-' Figure l is an inside view ofthe malleableiron shell or back of the box. Fig. 2 is an inside face view of the brass filler that fits inside of the malleable-iron shell. Fig. 3 is a longitudinal center sectional view of the malleable-iron shell. Fig. 4 is a side or edge view of the outside of the brass filler. Fig. 5 is a cross-section view of the malleable-iron shell and the brass filler in it and the filling of Bab-' bitt metal between them, taken on the dotted line X X, Figs. 3 and -t. Fig. 6 is an end view of the brass filler with its prongs and slots for Babbitt metal.

Like letters refer to like parts throughout the several views. I

Referring to the drawings, A is a malleableiron shell which forms the back or outside part of the box complete, which is of a standard shape outside with the usual head-flange a but the inside is hollowed out, so as to receive the brass filler-piece B, and it is provided with end cross-ribs to strengthen it laterally and two holes a a to match the pins b b, Fig. 4-, and a hole a near the center, into which to pour the melted babbitt t0 fill the box, also the bearing-strip surfaces or a and channels a a on its ends, as shown in Figs. 1 and 3.

B is a brass filler that fits into the shell A andfinds its bearing on the bearing-surfaces d a and caps over the ends of it, with its laterally or endwise when in use.

series of prongs I)? b in the series of channels a a in the ends of the shell A, thus forming chambers for babbitt between the prongs 1 and the ends of the shell. It is further provided with openings b h through the body of the filler from its bearing-surface to its back for the Babbitt filling C O, which fills all of the cavities and makes the parts of the box a solid mass. Said filler B is also provided on its back with pins b b, which match the holes a a and are riveted overon the outside of the shell A'to hold the filler B firmly to the shell A and prevent its shifting either In babbitting the box a mandrel is used of the desired size of the journal, end caps close over the chambers for babbitt on the ends, so that when the melted babbitt is poured in at the hole a all of the cavities are filled flush with the surface of the brass filler B, and the three metals form a solid mass, as shown in cross-section in Fig. 5. All of the internal surfaces having been tinned first, the Babbitt metal solders or adheres firmly to them in the operation of filling them hot, the desirable features of which are to present an evenly-divided wearing-surface of. the brass filler B and the Babbitt metal 0 to the journal and to completely border the Wearingsurface of the box with the brass metal of the filler B and also to so distribute the metal of the filler B and the Babbitt metal 0 over the wearing-surface of the box complete as to prevent the journal in wearing the box from coming in contact with the iron of the shell A. On the back of the filler the edges of all of the various openings for babbitt are chamfered, so as to form an undercut tohold the Babbitt metal in more firmly. I thus combine the desired Wearing qualities with durability and cheapness.

I have carefully described the parts of my invention and their relation to each other, so

as to set forth their advantages and desir- I What I do claim as new, and desire to secure by Letters Patent, is

1. In a journal-bearing, the combination of the exterior iron shell A, provided with its series of end channels a a opening for babbitting a internal bearing-surfaces a a and pin-openings a a to match pins 1) b, and the brass filler B, provided with its series of end prongs 12 b and pins b b to match the openings a a and undercut openings for babbitt t b and the Babbitt metal 0, filling all of the cavities between the shell A and the filler B, substantially as shown and specified.

2. In a journal-bearing, the combination of the brass filler B, provided with pins 1) b to match the openings at a, the series of end prongs 17 12 to match the series of end channels a aithe undercut series of internal openings b 19 for Babbitt metal, having an unbroken border of brass, the exterior iron shell A, provided with its pin-openings a{ a, to match the pins Z) 1'), its opening a for babhitting, its internal bearing-surfaces a a and its series of end channels at of, to match the series of end prongs b b and the filling of Babbitt metal 0, making an even equal wearing-surface of babbitt and brass, substantially as shown and described.

3. In a journal-bearing, the combination of the exterior shell of iron A, with its bearing-surfaces, pin-openings and series of end channels, the brass filler B, with its pins, its series of end prongs, and openings for Babbitt metal, and secured together by riveting the said pins, and the filling of Babbitt metal C, so that the shell A, the filler B, and the babbitt 0, form a solid mass of metal, substantially as shown and specified.

In testimony whereof I affix my signature in presence of two witnesses.
